Bose Amp and steering wheel controls

[danish]

I replaced the CDR23 HU with one of those Chinese (Seicane Android) unit.

When I put the key in the ignition, the controls on steering wheel work fine, but when I start the engine, the controls don’t work.  Also, I noticed that if I wait to start the engine (say 10+ seconds) after putting the key in the ignition, there is no sound from the Bose amp, but if I start it right away, it works.  I also hear that thump sound from the amp when I remove the key from the ignition.

 

The MOST adapter (in turn, the amp) wiring is getting power from the Canbus adapter.  It is switched, meaning, it will not work unless there is a key in the ignition.  Does it have to be unswtiched power connection?  If so, any reason why?  And could this tapping power from the canbus adapter in parallel causing the steering wheel controls to not work when engine is running?  Sorry, I am not an electrical engineer, so some of these questions may sound stupid.

 

Any suggestions, besides suggesting to replace the sh!tty Bose amp?:)

Thanks, do you use bagoo manyfacturer in advanced settings? 

Also the sound doesn t work with my phone and gps when the radio is playing, any ideas what’s the issue?

Sorry, don’t know what could be causing the issue with phone sound.  Perhaps try connecting via the A2DP app first, if you are using Bluetooth.
